锚固结构是边坡防护中常用的一种工程措施。然而由于依靠工程经验设计防护方案,选取锚杆支护参数,未能做到合理优化设计,造成工程资源的极大浪费,并带来很大的安全隐患。以杭金衢K95高边坡为研究背景,通过数值模拟对主要锚杆参数对边坡安全系数的影响进行了分析,并通过正交试验确定该边坡的锚杆支护参数,优化锚杆布置方案,达到锚固效果兼顾经济型的目的,为类似工程提供借鉴。
Anchorage structure is a commonly used engineering measure in slope protection. However, due to relying on engineering experience design and protection program, select the bolt support parameters, failed to do a reasonable optimization of design, resulting in a tremendous waste of engineering resources, and bring great security risks. Taking the high side slope of K999 Jin-Qu-K type as the research background, the influence of the main anchor parameters on the safety factor of the slope was analyzed by numerical simulation. The parameters of bolt support were determined by orthogonal test, , To achieve the anchoring effect of both economic purposes, to provide reference for similar projects.
